Question

If 25g of calcium carbonate is heated calculate the number of moles of calcium carbonate used

Answer 1

$\huge\mathfrak{Solution :- }$

★ Molecular weight of Calcium carbonate (CaCO)

=> 40+12+(16×3)

=> 100 g

Given,

Weight : 25g

Therefore,

Number of Moles

$= > \frac{Weight}{Molecular \:mass}$

$= > \frac{25}{100}$

$= > 0.25 \: moles$

★Hence, O.25 moles of calcium carbonate used.
